Mentalizing is not only at the heart of human existence but at the heart of human society. The distinguished editors of this second edition of Handbook of Mentalizing in Mental Health Practice have assembled a team of experts who make accessible the ground-breaking practical, research, and theoretical approaches to this transdiagnostic concept—giving weight to its powerful applicability across a variety of disorders, communities, and populations. Of utmost importance to practitioners, this book provides coherent, tried-and-tested approaches to both common and hard-to-treat conditions. In addition, the authors present a conceptual framework for clinicians who are helping patients to consider their own thoughts and feelings and to differentiate them from the perspectives of others. As the applicability of mentalization-based treatment reaches across a growing range of evidence-based uses, this pioneering model helps clinicians to understand the social processes embedded in relationships between parents and children, the experience of childhood adversity, and the nature of learning within interpersonal communication—as well as an understanding of the emergence and maintenance of mental disorder. The book's foremost experts offer profound insights that veteran clinicians and trainees alike will find eminently useful. The Handbook of Mentalizing in Mental Health Practice, Second Edition, is an indispensable guide to the current state of clinical work and research on mentalization-based approaches in mental health practice.
